I also added an If statement to check to see if the current version is installed already and if it is to do nothing. This way i can set my script to run once a week on all my computers.

Thanks for the script!

Is there a reason I shouldn't just do something like:

download_url="http://go.microsoft.com/fwlink/?LinkID=229322"
sl_dmg="silverlight.dmg"
/usr/bin/curl -sfL --output "$sl_dmg" "$download_url"

which would just let curl follow the redirect and download, rather than

download_url=$( curl  -sfA "$UGENT" "http://go.microsoft.com/fwlink/?LinkID=229322" | awk -F'"' '{print $2}' | sed '/^$/d' )
sl_dmg="silverlight.dmg"

I adapted the script from @kenergy with one we already had for Flash and this is what we use. You'd need to modify the Log and DMG download locations for your own environment. The script will also, if it has updated Silverlight, ensure that it is properly enabled. We've had issues with it getting turned off in Safari.

why did you exit if there's no version found? I removed it and now it can always be installed...

Anyway, just to let you know - great script btw!

@iJake This script worked well with slight modification. I added the signature check from the initial script.

Unfortunately the script throws failed because the geniuses at Microsoft must have not updated the version name correctly. Downloading the latest currently available reads 5.1.50905.0 but when installed reads 5.1.50901.0, even when installing manually.

@ktermin

This script should be run from the JAMF server and scoped out to the device.

I've been running this version for months without issues and $4 is still running 5.1.50901.0.

@ktermin It can be run locally, but you can't just drop it as is into Terminal. To test it locally first, use the jamf binary. Example:

sudo jamf runScript -script <script_name_including_extension> -path <path_to_script_minus_script_name> -p1 <parameter 4 string>

Just replace the items between the < & > brackets with the correct information.

Incidentally, @millersc should probably update his script to check for a string passed to $4 and fail with a more descriptive error message if one isn't passed. As it is, it's not downloading anything and hdiutil has no DMG to work with, which is why it's throwing that error.

Even though there is an error, it still installs but seems to be the old version. New version being Silverlight 5 Build 5.1.50907.0 Released June 13, 2017.

I read thru the thread and seems there was an issue but was fixed. Is this not the case? Thanks!

Microsoft has made updates to the Windows version, not the Mac version. It is still at 5.1.50901.0. I believe that is why your getting an error.

This is the result of the script from yesterday:

FYI - Microsoft no longer updates or supports Silverlight for Mac as of 12/31/2016.
Also, the last supported macOS version is 10.11.

exit 0

Hi iJake,

why did you exit if there's no version found? I removed it and now it can always be installed...

Anyway, just to let you know - great script btw!

@peterloobuyck We only wanted to update clients that already had it in our case. Glad you found it useful and were able to modify it.

@iJake This script worked well with slight modification. I added the signature check from the initial script.

@psd_martinb I noticed that MS problem a week ago and modified my script. I changed it to use $4 variable now instead of reading the MS history page. Been working good for a week now.

@millersc Awesome! Thank you

@millersc Thanks!

Got the updated script from guthub.

And get this error when running locally.

~/Documents/Casper Resources/Scripts/silverlight.sh

curl: (3) <url> malformed
hdiutil: attach failed - No such file or directory
hdiutil: detach failed - No such file or directory

@ktermin

This script should be run from the JAMF server and scoped out to the device.

I've been running this version for months without issues and $4 is still running 5.1.50901.0.

Steve

@millersc

Cool. I will test that way. Usually I run the script locally to troubleshoot.

Thanks for the heads up.

@ktermin It can be run locally, but you can't just drop it as is into Terminal. To test it locally first, use the jamf binary. Example:

sudo jamf runScript -script <script_name_including_extension> -path <path_to_script_minus_script_name> -p1 <parameter 4 string>

Just replace the items between the < & > brackets with the correct information.

It is installing version 5.1.50901.0.

This is the error it is outputting:

Script result: Microsoft Silverlight is not installed

Even though there is an error, it still installs but seems to be the old version. New version being Silverlight 5 Build 5.1.50907.0 Released June 13, 2017.

I read thru the thread and seems there was an issue but was fixed. Is this not the case? Thanks!

I also have 5.1.50901.0 installed which appears to be the most recent according to https://www.microsoft.com/getsilverlight/Get-Started/Install/Default

https://www.microsoft.com/getsilverlight/locale/en-us/html/Microsoft%20Silverlight%20Release%20History.htm#SL_5_1_50907

Microsoft has made updates to the Windows version, not the Mac version. It is still at 5.1.50901.0. I believe that is why your getting an error.

This is the result of the script from yesterday:

Executing Policy Install Silverlight Latest

Thank you iJake for the script. It worked like a charm.
